looking to buy a controller with the display can any one recommend one not to sure about the plugs to the Bafang BPM Motor it as a plug with 6 pins the controller thati have seen all seem to be 9 pins
thanks for your help on this i will take a pic soonThe six pin plugs are old style and use an internal speed sensor.
Show us a pic the cable end that connects to the controller Phase and the three sensor wires, depending on this connection you might be able to use a sinewave Kt controller and display.
Hi nealh im thinking when my old battery dies i was going to buy a 48v battery would this controller be ok https://www.ebay.co.uk/itm/283513202378I see six three thicker phase and there speed sensor wire Red, Blk & Wh.
You need a sensor less controller with the speed sensor connector like this one, it has a PAS connector, throttle connector if needed and the LCD connector. Select any Kt lcd display to use.
Sensorless Brushless Motor Controller DC 24V/36V 250W 6-FET 15A KT Squ – TorqueTech
If you want cheaper try ali express.
You may have to do some wiring as the connectors may not match yours.
Hi nealh i went for the KT-LCD3 is there any think i need to know when i switch it on for the firts time and what seting do i useYes it's one of the 9 mosfet ones and dual voltage, add a nice KT lcd and voltage will be recognised automatically.
ok thanks it looks like all the plugs need doing lolDirectly solder the wires together and shrink the joint.
thanks nealh throttle works but PAS. is not working and breaks when i pull out the break connector the throttle does not workPAS needs connecting to be legal and for pedal assist to work, throttle will work without PAS.
Yes wire sequence on sp sensor need to match.
